The 2018 campaign, according to Mário Ramos, reached an index of 90%, but among children and pregnant women, who are part of the at-risk group, the coverage was about 80% of the target.

"It is also necessary to consider the response time after the dose, which is 10 to 15 days, but it is important to note that the vaccine itself is unable to cause the flu or similar symptoms."
The people most likely to have an aggravated condition are those who are not vaccinated and who belong to the at-risk group, such as children up to age five, the elderly and people with chronic diseases . According to the municipal health service, the victims of influenza A who died this year are on average over 50 years old and have comorbidities such as cardiovascular diseases, diabetes, chronic lung diseases, obesity, cognitive diseases and neoplasias [19659002] "Normally, when the person has a health problem, the underlying disease is decompensated by the action of the virus, the risk is increased primarily for those with cardiovascular or pulmonary disease."
